In the NOBLE EIGHTFOLD PATH by Bhikkhu Bodhi,
there is a very relevant quote under RIGHT SPEECH :
(4) Abstaining from idle chatter (samphappalapa veramani).
He avoids idle chatter and abstains from it. He speaks at the right time, in accordance with facts, speaks what is useful, speaks of the Dhamma and the discipline; his speech is like a treasure, uttered at the right moment, accompanied by reason, moderate and full of sense.
Idle chatter is pointless talk, speech that lacks purpose or depth. Such speech communicates nothing of value, but only stirs up the defilements in one’s own mind and in others. The Buddha advises that idle talk should be curbed and speech restricted as much as possible to matters of genuine importance. In the case of a monk, the typical subject of the passage just quoted, his words should be selective and concerned primarily with the Dhamma. Lay persons will have more need for affectionate small talk with friends and family, polite conversation with acquaintances, and talk in connection with their line of work. But even then they should be mindful not to let the conversation stray into pastures where the restless mind, always eager for something sweet or spicy to feed on, might find the chance to indulge its defiling propensities.
The traditional exegesis of abstaining from idle chatter refers only to avoiding engagement in such talk oneself. But today it might be of value to give this factor a different slant, made imperative by certain developments peculiar to our own time, unknown in the days of the Buddha and the ancient commentators. This is avoiding exposure to the idle chatter constantly bombarding us through the new media of communication created by modern technology. An incredible array of devices — television, radio, newspapers, pulp journals, the cinema [and Facebook / Twitter] — turns out a continuous stream of needless information and distracting entertainment the net effect of which is to leave the mind passive, vacant, and sterile. All these developments, naively accepted as “progress,” threaten to blunt our aesthetic and spiritual sensitivities and deafen us to the higher call of the contemplative life. Serious aspirants on the path to liberation have to be extremely discerning in what they allow themselves to be exposed to. They would greatly serve their aspirations by including these sources of amusement and needless information in the category of idle chatter and making an effort to avoid them.
